Patent GB-1467126-A (GB)
Title: Current stabilizing arrangement
IPC: G05F3/26
Filed: 1975-03-07
Abstract: 1467126 Automatic current regulation PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 March 1975 [11 March 1974] 9573/75 Heading G3X An arrangement for stabilizing a current with respect to temperature variations includes a first circuit with input, output and common terminals producing at its output a current with a negative temperature coefficient. A second circuit, having two terminals connected respectively to the output and common terminals of the first circuit, carries a current which has a positive temperature coefficient arranged to compensate for first order temperature effects. The input and output currents of the first circuit are connected to respective terminals of a circuit having two branches in which the currents are in a fixed ratio, independent of temperature and voltage. As shown in Fig. 3. a current mirror T7, T8, T9 supplies current to the input A of a three-terminal circuit, Fig. 1, which produces an output current I1 at terminal A' with a negative temperature coefficient. The input terminal G' of the current mirror is also connected to one terminal C of a twoterminal network, Fig. 2, with a positive temperature coefficient of current. Resistors R1, R2 are chosen so as to balance the temperature coefficients to the first order. A current squaring circuit, Fig. 4 (not shown), may be included in the arrangement, Figs. 5-6 (not shown), if second order compensation is required. The arrangement may be constructed as a monolithic integrated circuit and used to supply a frequency-stable oscillator or a digitalto-analog converter.

Title: Unsaturated nitriles
Filed: 1959-03-19
Abstract: In a process for the preparation of a ,b -unsaturated nitriles by atomizing a -hydroxy-carboxylic acid nitriles or amides with a hydrous inorganic acid, e.g. phosphoric acid (as dehydration catalyst), into a reaction chamber at 400 DEG C. to 700 DEG C. according to the parent Specification, the process is improved by atomizing the reaction mixture through a nozzle which ends in the centre of an annular slot through which a current of hot inert gases is introduced into the reaction chamber and immediately mixes with and heats the atomizing reaction mixture, and then carries it through the chamber.  Examples 1 and 2 relate to the preparation of 1-cyanbuta-1,3-diene from crotonaldehyde cyanohydrin and acetaldol cyanohydrin, respectively.  Example 3 relates to the preparation of 2-cyanobuta-1,3-diene from methyl vinyl ketone cyanohydrin.  2 - Cyanobuta - 1, 3 - diene may alternatively be prepared from the cyanohydrin of methyl-acetyl-carbinol (acetoin) or of 3-ketobutan-1-ol.  Example 4 relates to the preparation of 1-cyanocyclohex-1-ene from cyclohexanone cyanohydrin.  Examples 5, 6 and 7 relate to the preparation of acrylonitrile from lactic acid nitrile, and Example 8 describes the preparation of the same compound from lactic acid amide.  The preparation of b -ethylacrylonitrile, crotonic acid nitrile, and methylacrylonitrile from hydroxy-valeric acid nitrile, a -hydroxybutyric acid nitrile and acetone cyanohydrin, respectively, is mentioned.  The reaction gases leaving the reaction chamber may be cooled by direct injection of aqueous phosphoric acid, whereby only part of the unsaturated nitrile product is condensed, and the remainder being removed from the chamber in the cooled gases. These cooled gases are subsequently washed with water, and the wash-water is worke-up by distillation.

Title: Method and Apparatus for Expanding a Gas.
Inventor: SIXSMITH HERBERT
IPC: F25B9/06
Filed: 1966-03-04
Abstract: 1,177,651. Refrigerating. H. SIXSMITH. 3 March, 1967 [4 March, 1966], No. 9660/66. Heading F4H. In a refrigeration system a gas is expanded by establishing a gaseous piston adjacent one end 11 of a chamber 10, introducing a predetermined mass of gas through an inlet line 12 to move the gaseous piston away from end 11, closing a valve 20 in inlet line 12 and continuing to move the gaseous piston away from end 11 so as to expand said predetermined mass of gas. End 11 has an outlet line 13 while the other end 14 of the chamber has an inlet line 15 and an outlet line 16, valves 21, 22, 23 being respectively provided in lines 13, 15, 16. The gaseous piston is established in a compressed state adjacent end 11 by supplying high pressure gas through line 15 with valves 20, 21, 23 closed. Valve 22 is then closed and valves 20 and 23 opened so that high pressure gas from inlet 12 moves the gaseous piston upwardly while gas is exhausted at low pressure through line 16. Valve 20 is then closed while valve 23 remains open so that the piston continues to move upwardly and the gas therebeneath is expanded. The expanded gas is exhausted through line 13 by admitting gas through inlet 15, and passed through a load 24 and a heat exchanger 27 to cool gas in line 12. The gas is compressed and cooled at 29 before being returned to line 12. The gas exhausted through line 16 is compressed and cooled at 33 before returning to line 15, lines 15 and 16 include flow regulators controlled by a device 35 in response to the temperature at the midpoint of either heat exchanger 27 or chamber 10. Alternatively the relative durations of the phases of the cycle or the degree of compression at 29, 33 may be controlled. Helium is employed as the working medium and the upper end of the chamber may be cooled to 12‹ K. by auxiliary refrigeration. Chamber 10 may be filled with porous material.

Arranged in the conduit is a holding valve which, when the conduit is connected to the tank, maintains a minimum pressure in the conduit branch leading to the machine unit. A pressure sensor arranged in this conduit branch determines the actual value of the conduit pressure. If this decreases with respect to the minimum pressure predetermined by the opening pressure of the holding valve, which is determined by a comparison device, this is an indication that the conduit section has a leak, if only a small one.

Abstract: PROBLEM TO BE SOLVED: To improve the characteristics of a photovoltaic infrared detecting element, especially, to reduce the noise of the element and improve the thermal stability of the element by preventing a part having a crystal defect or damaged by ion implantation from becoming the passage of a tunnel current and forming a laminated CdTe/HgCdTe structure without exposing the interface of the structure to the air through simple means in a method for manufacturing the infrared detecting element. SOLUTION: A part 2A having a crystal defect or damaged by ion implantation and formed in an HgCdTe photoelectric conversion layer 2 is prevented from becoming the passage of a tunnel current, namely, a leakage current is prevented from flowing by making the energy band gap of the part 2A relatively larger than that of the perfect crystal section in the layer 2 by heating- treating the layer 2 in a Cd atmosphere and, at the same time, a surface protective layer 3 composed of CdTe is formed on the surface of the layer 2.
